Title: Method and circuit for the automatic zero-point correction of clock-controlled measuring systems
Inventor: HOFFMANN JUERGEN DIPL ING
IPC: G01R19/32
Filed: 1987-02-13
Abstract: These measuring systems are, for example, those in anaesthetic and therapeutic breathing apparatus and monitors, in which the measurement values can be output continuously or intermittently. It is the aim and object to compensate for a false signal produced by parameter effects, which causes a zero-point deviation. This is essentially achieved by means of an inverting and a non-inverting circuit arm which is connected or disconnected by means of an electronic switch or makes it possible to store a difference voltage (zero-point deviation) in order to utilise it for the correction.

Patent DE-3722412-A1 (DE)
Title: Open grid retaining wall of concrete blocks
Inventor: KWIATKOWSKI HERBERT DIPL ING
IPC: E01F8/02
Filed: 1987-07-07
Abstract: Concrete dry retaining walls consist of solid blocks or formwork blocks. The latter, although only a concrete envelope, are relatively heavy and punch their way into the earth with their narrow-edged profile. Without a foundation, the wall is unstable. Yet as a gravity wall after earth filling it is too light, since earth scarcely loads the blocks but only the natural soil. The wall can only be of a small height or pronounced back-stepping is necessary. Then there is no longer a wall. The grid retaining wall according to the invention is the combination of a keyed, drawer-like concrete block, composed of two relatively light block halves, with an earth filling loaded by solid blocks so that the wall becomes a genuine gravity retaining wall. The rear side of the wall forming a narrow-edged concrete grid cuts into the slope and with the earth becomes a static, mutually supporting unit. The partly open front side of the wall permits a proportioned earth overflow of the pushing slope so that no slope pressure can build up.   The large-area ground support of the wall dispenses with a concrete foundation on account of the low ground pressure. The wall can flexibly absorb any soil movements. Any horizontal adaptation to the terrain is also possible.

Title: Method and device for taking soil samples
Inventor: ROEDEL GEHARD
IPC: E21B25/06
Filed: 1987-12-21
Abstract: It is intended to allow an operator to take clean and more accurate samples which can be transported easily and processed in the laboratory in a better fashion by using a specialised device which can be transported easily and which avoids hard manual work. The operator takes samples using a specialised mandrel which operates, for example, in a vibrating manner. The sample is squeezed into a sleeve which, on the one hand, acts as a packaging of the sample immediately after the sampling process and which, on the other hand, can be used as an auxiliary for the immediate recording of characteristic data (for example soil density, moisture content and CO2 content). Immediate packaging of the sample prevents the sample from drying out; the sample does not lose any constituents and can be processed in the laboratory in a space-saving and more accurate manner.

Title: Hyperbolic-perspective method for production of computer-aided pictorial simulations of three-dimensional reality on the screen (also for production of hard copies), or in the character area
Inventor: KOLLMANN MARTIN PAUL JOACHIM
IPC: G06T3/00
Filed: 1988-03-30
Abstract: The method supersedes the method of linear perspective which has been used for 500 years, the main defects of which are distortion at the edge and inexact localisation of the vanishing lines. Only the present state of computer technology makes it possible to use the method even in dynamic applications, since writing hyperbolae has taken too much time until now. To be practicable, the method generally assumes the use of computers. It is based on the fact that all vanishing lines, whether they are frontal or run into the picture, run on conjugate hyperbolae, and each section of vanishing line can be localised by four parameters. Application areas are: CAD (computer-aided design) (drawing and screen), visual training aids, screen demonstrations, etc.

Patent DE-3818313-A1 (DE)
Title: Hydraulic clamping ring
Inventor: SCHAAF MARTIN
IPC: B24B45/00
Filed: 1988-05-30
Abstract: The invention relates to a hydraulic clamping ring in which several pistons are arranged uniformly distributed parallel and concentric to the axis of rotation in cylinder bores, the pistons, through the admission of pressure medium in the cylinder bores connected to one another, exerting a clamping pressure on a tool or workpiece rotating with the axis. The object of the invention is a space-saving design of such a clamping ring, in which at the same time the connection between the cylinder bores is possible in a simple manner and without additional space requirement and means for the positive piston return can be provided. According to the invention, this is achieved by the use of stepped pistons, the smaller diameter steps of which form guide journals. By this stepped arrangement to form a piston part and a guide journal, sufficient space for the arrangement of an annular passage connecting the cylinder bores is obtained at the side of the guide journal, so that the clamping ring can be designed with minimum width and yet the pistons are effectively guided, since the decisive ratio for this of piston diameter to guide length is unchanged. At the same time, without additional space requirement and with the least possible cost in terms of production, this permits a connection between the cylinder bores by branch bores which are made diagonally in the sections of larger diameter of the cylinder bores up to the centre of the distance between ...

Title: Continuous steel-casting mould
Inventor: KAISER HANS PETER
IPC: B22D11/05
Filed: 1988-09-29
Abstract: In a continuous steel-casting mould with two broad-side walls arranged opposite one another and narrow-side walls which are clamped between the broad-side walls and can be displaced to adjust the format width, clamping forces generated by compression springs are altered by means of hydraulic cylinders arranged in parallel. To provide an operationally reliable mould in which it is possible to set the pressing forces accurately, the force of the compression springs (8, 28) is designed to correspond to the pressing force required for the adjustment of the narrow-side walls (5, 25). The pressure-medium cylinders (9, 29) can be pressurised in such a way as to increase the pressing force. <IMAGE>
